Embodiments are provided for customizing an audio system of a vehicle. An example computing device for customization of an audio system of a vehicle includes a display configured to present a user interface, a processor, and a storage device storing instructions executable by the processor to generate the user interface for presentation via the display, and receive user input to the user interface requesting one or more adjustments to an audio system, the one or more adjustments including instructions to tune an amplifier of the vehicle by adjusting digital signal processing (DSP) settings of the amplifier. The instructions are further executable to transmit the one or more requested adjustments to a communication interface of the amplifier of the vehicle, the adjusted DSP settings being stored in the amplifier and retrievable by the computing device.
